- Latest Emscripten SDK (http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html)
- CMake 3.4.3 or higher (https://cmake.org/download/)
- htslib (included in the source tree)
- zlib (included in the source tree)
You can clone htslib-js by issuing below command:
$ git clone --recurse-submodules https://github.com/eilslabs/htslib-js
Please make sure to use --recurse-submodules option here, to clone the submodule htslib required by htslib-js.
To build htslib-js, firstly you need Emscripten SDK and CMake. You can download sdk via this link: http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html and https://cmake.org/download/. We recommend to include CMake in system PATH or local user's PATH for convenience. On Windows, you may also need MinGW http://www.mingw.org/ to use GNU build tools.
After install Emscripten SDK, required environment variables should be initialized by running:
In POSIX environment:
$ emsdk activate
$ source emsdk_env.sh
On Windows:
> emsdk activate
After that, build htslib-js by running:
In POSIX environment:
$ emcmake cmake -DCMAKE_BUILD_TYPE=Release .
$ make
On Windows:
> emcmake cmake -DCMAKE_BUILD_TYPE=Release . -G "MinGW Makefiles"
> mingw32-make
And then the compiled JavaScript files and example html files will be generated under 'examples' directory.
